Love Dinotopia but please don't post art on DA that was not made by you. If you have to give another artist copyright credit, you're violating DA's terms of service as well as James Gurney's copyright.. copyright means the artist is the one who has the exclusive right to make copies, i.e. to post it.

DA is for users to share their art, not for people to upload other peoples' art, even if the intent is to appreciate.
